Outer Limits 4x4 Board

hey guys i recently purchased a gu patrol coil cab ute tho i want more whistle out of the exhaust ....... it already has a 3 inch mandrel bent exhaust thats sounds great but you can only just hear the whistle (looks like a factory dump pipe) and i added a K and N filter in the factory box. its currently running 8 pound of boost also. i dont have a snorkle yet but that is on the shopping list for later...

ive been told to wind the boost up to bout 12 psi and have it dynoed and ive been told a snorkle will make it wistle like a bitch but i dont want to fork out money for these things if it isnt going to make a true TURBO DIESEL sound..... im really happy with the economy at the mo too.....

any help will be greatly appreciated cheers guys

First thing i'd do is fit a true 3 inch dump pipe in there , dieseltec on here does them and sends them out to where you are .

Also does it have mufflers or a hotdog ?

do you want performance or just whistle?

if your just after pure whistle then add compound turbos

I have fitted one of these, I modded the dump slightly with a die ginder behind the swinggate. I reshaped the flange to allow the swinggate to open more. I also added a socket for the pyro.

To fit the exhaust to a ute the engine pipe needs to be modded to clear the safety loop from the cab to chassis on the LHS of the T case.

As you already have a 3" exhaust you can just get the dump though, it does make a big difference to exhaust temps, and seems to give better responce.

hey guys cheers for the advice, i definately wont be putting that fake turbo blow off valve thing on cause they are as gay as elton john... as i said i already have a 3 inch mandrel system. the dump pipe sounds like a good idea. i dont have an mufflers or hotdogs in the exhaust.... any idea how much a dump pipe from dieseltech is??? cheers

OMG its gonna be fully sik uleh, just like my cousins brothers uncles VL mate, wid da hektic dose wwwuuuuu tu tu tut tututu

blow this as you drive along.

haha too funny! i dont want it to sound like a street car i just want it to sound like a turbo diesel should lol. is there any chance my turbo is on its last legs? the car has done 178000klms and i dont think its been replaced

where bouts on the sunny coast are u? i have a gu ute your most welcome to.....listen to ..... if need be. 3in straight trough with dump pipe and factory exhaust route. it doesnt "whistle" loud, but has a distinct diesel note too it. its hard to get a feel for the noise when your driver

cheers

not all turbo diesels have a loud whistle through the exhaust.. I'd be more worried bout performance and use than a whistle.

thanks guys for the info and vanbox thanks heaps tough truck you have!!!! mine sounds bout the same as yours. going get a 3 inch dump pipe and bump the boost up and see how that goes with a dyno tune. cheers for all the help guys and if anyone else has anymore ideas please tell cheers

If you find a workshop selling tubo whistle cheap, let me know! I'm after about 300 grams of 85dB whistle.

should whistle good enough is it straight thru ??? if u have mufflers that is ur problem

I have 107db of whistle, make me an offer.

for whistle from idle to red line = BB turbo with 3" exhaust no mufflers, otherwise see post above this one.

BAHAHAHAHAHAHAHAHAHAHAHA.................bahahahahahahaha

cheers

I wasn't really after the 107dB type, but I'll trade you 4psi boost and a full 10L bucket of high octane LPG.

Is your whistle compatible with my double bypass hyclone setup?
